My boyfriend and i were walking to lunch and he looked up because he heard a helicopter. right next to the helicopter we noticed 4 small orbs flying in erratic patterns. the helicopter left and we watched the orbs fly playfully around eachother changing directions almost constantly. they flew north then came back northwest and then flew north again until they were out of sight.
